I write about many subjects typically surrounding my kids, including fundraising, gifts for children, vacations, and Boy Scouts.
General Lego Terms
If all you know about Lego is what you see in the local Target or Walmart toy aisle, then you are missing about 80% of what is out there. To navigate around the rest of the Lego world, you'll need to learn some terms and abbreviations.
- Bionicle - A type of set that is typically a large figure creation.
- Brick - a single Lego part. Sets are usually measured in the number of parts or bricks the set contains.
- Bulk Lego - Bulk is a term used to describe lego that isn't sorted (maybe by color or type) and is contained within a bin or container. Bulk is typically measured in pounds (US) or kilos and can be found on most auction sites or online market places.
- Duplo - Duplo are Lego that are twice as big as their normal counterparts. These are big enough for toddlers to build.
- Lego - The Lego Group is a toy company headquartered in Billund that makes interlocking plastic bricks.
- Legos - The plural of Lego is not Legos. A lot of purists get annoyed with this term and will tell you the plural is Lego bricks. Instead of saying Lego bricks, Legos is used a lot.
- My Own Creation - A MOC is something you created yourself that you didn't use instructions to build.
- Set - This is what you buy in the toy aisle. Each box has a number that identifies the set.
- Studs - The little circles on top of a brick that allow the bricks to connect to each other. These are also used to determine the size of each brick. For example a 2x4 indicates the brick is 2 studs wide by 4 studs long.
- Technic - A type of Lego brick that is utilized in building moveable sets. It includes gears and axles.
- Theme - A group of sets built around the same genre like Star Wars, Harry Potter, City, Ninjago, and many others.

- BigFig - These are larger figures like the Hulk, Trolls, Thanos, Rangkor, Jabba the Hut, etc.
